Application filed January 25, 1926. Serial No. 83,643.

This invention comprehends the provision of foot controlled accelerating means for internal combustion engines, and is primarily intended for Ford automobiles, the invention being in the nature of an attachment and mounted in a manner to permit the floor boards to be removed without detaching the saidaccelerating means, and also without the necessity of cutting the floor boards or mat for installation.

The nature and advantages of the inven tion will be better understood when the fol= lowing detailed description is read in connection with the accompanying draw ngs, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference'indica-te similar parts in the several views, and wherein: I

Figure 1 is a fragmentary view of a mo-, tor vehicle showing the application of the invention.

Figure 2 is'a view showing how the foot and hand operated elements are connected with the throttle valve lever for independent operation. 1

Figure 3 is a perspective view of the foot operated rock shaft and foot rest.

Figure 4 is a perspective view of the support for the pivoted element of said attachment. 7

Figure 5 is a perspective view of sald pivoted element.

Figure 6 is a View of the rod connected with the throttle valve lever and used in conjunction with both the hand operated element and the foot operated rock shaft.

Figure 7 is a detail view of the bracket for said foot rest.

Referring to the drawings in detail, 10 indicates an internal combustion engine of the type used in automobiles, while 11 and 12 represent the dash board and floor boards of the vehicle. The throttle valve lever is indicated at 13, and the attachment forming the subject matter of the present invention is connected with this lever 13 so it can be operated by a hand lever or by the foot of the driver.

The attachment includes a rod 14: which is pivotally connected at one end with the throttle valve lever 13. as shown in Figure 2, the lower end of this rod being offset as at 15 and then extended as at 16 terminating to provide an eye 17. A chain or other flexible element 18 connects the eye 17 of this rod with the offset extremity 19 of a hand operated rod 20, so that the throttle valve can be controlled by the hand independently of the foot operated means to be presently described.

The foot operatedmeans includes a pivoted element formed from' a single length of wire'and indicated at 21. At one end this element is formed with an eye 22 which i surrounds the rod 14: and cooperates with the offset portion 15 of said rod to operate the throttle valve incident to the operation of the foot pedal 23. This'pivoted element is also formed adjacent its other'end with a coil 24 which is employed to support the element 21 for pivotal movement on the portion 25 of a fixed support, clearly illus-- trated in Figure 4. This support is also formed from a single piece of wire and includes a portion 26 having an offset extrem ity 27. and is formed with a loop 28 where the portions 25 and26 are associated. This loop 28 is adapted to be supported on the bolt-29 behind the hexagon nut 30 which is utilized to attach the water pipe 31 with the motor, the association of these parts being clearly illustrated in Figure 1. The final convolution of the coil 24 is extended to provide an eye 32, and this eye is connected by a rod 33 to the adjacent curved extremity 34: of the rock shaft indicated at 35. The

rock shaft is mounted on the dash board 11 in a manner to be presently described, and supports the pedal 23 which is normally held spaced above the floor board by means of a coil. spring 36, one end of which is connected with the eve 32 of the pivoted element, while the other end is connected with the offset extremity 27 of the support for this element. As clearly shown in Figures 1 and 3, the rock shaft is iournaled in a bracket or bearing plate 37 which is secured to the dash board 11, while mounted on the same board adjacent the bracket 37 is a similar bracket 38 which has pivotally connected thereto a foot rest formed from a single length of wire indicated at 39 and 105.

necessity of cutting the floor boards or mat to accommodate the same, and that both the pedal 23 and the foot rest 39 can be elevated to permit the floor boards to be removed and replaced without detaching the foot controlled accelerating means.

Having thus described the invention, what is claimed as new, is

1. Foot controlled accelerating means for internal combustion engines, embodying a rock shaft, a pedal carried thereby, a rod connected with the throttle lever of the carburetor, a hand operated element, a chain connecting the rod and said element whereby the throttle can be operated independently of said pedal, a support formed from a single piece of wireand mounted on said engine, an element mounted for pivotal movement- 'on said support, a coil spring terminallyconnected with said element and the support, means connecting said element with the rock shaft, and said element being connected with said rod and cooperating therewith to operate the. throttle by said pedal independently of said hand operated element.

2. Foot controlled accelerating means for internal combustion engines, embodying a vide an eye, an element connecting the eye with said rock shaft, whereby said element is actuated upon depression of said pedal, and an eye formed at one end of said ele ment and receiving said rod, and arranged to cooperate with the offset portion of the latter to operate the throttle independently of said hand operated element.

3. Foot controlled accelerating means for internal combustion engines, embodying a rock shaft, a pedal carried thereby, a rod connected with the throttle lever of the carburetor and including an offset portion, a hand operated element, a chain connecting said rod and element, a fixed support attached to the engine, saidsupport being formed from a single length of wire and including right angularly disposed branches, a loop formed at the point of juncture between said branches and adapted to embrace one of the engine bolts, whereby the support is attached to the engine, an element formed from a single length of wire and including an offset coil mounted on one branch of said support for pivotal movement, the final convolution of said coil being extended to form an eye, an eye formed at the other end of said element and receiving said rod and arranged to cooperate with the offset portion thereof, a rod connecting the rock shaft with the eye forming part of said coil, and a coil spring terminally connected with the last mentioned eye and the other branch of said fixed support for'the purpose specified.

In testimony whereof I afiix my signa ture.

FRED HERMAN KRUEGER.
